To all 'whom t may concern.'

Be it known that 1, GEORGE M. EATON, a

citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny 'and State of Pennsylvania, have invented a new and useful improvement in Electric Locomotives, of which the following is a specification.

My invention relates to electric locomotives, and it hasfor its object to provide a locomotive of exceptionally construction. E

Another object 'of the invention is to provide means for resiliently connecting the light but strong journalboxes for the end driving axles to' the locomotive frame independently of thel means for resi-liently supporting the said frame upon the journal boxes, so that the said axles and journal boxes may be capable of movement horizontally with respect to themain frame of the locomotive.

YA further object of the invention is to so l mount and support the driving motors for the end axles of the locomotive that, while the motors are resiliently supported from the main frameof the locomotive, they are capable of free movement with respect thereto and permit of the above-referredto horizontal movements of the end axles and journal boxes with respect to the main frame.

A still further 'object ofthe invention is to provide atrussed locomotive frame to which bearings or seats for equalizing beams may be readily attached. V

Other objects of the invention will more specifically appear in lconnection with the following detailed description of the' locomotive.

Figure l of theaccompanying drawings is a view in side elevation of a part of a locomotive that embodies the present invention. Fig. 2 is a plan view of the truck of the'locomotive shown in Fig.v 1. Fig. 3 is a view in end elevation and in section of the locomotive shown in Fig- 1. Fig. 4 is an enlarged side and sectional view `of a 'part of the locomotive, showing particularly one of the motors and its manner of support.

Fig. 5 is an enlarged plan and section view` of a part of the locomotive, showing particularly one of the end motors and the oen-l tering means therefor. Fig. 6`is 'a perspective view of one of the yokes or arches to Specification 'of Letters Patent. i Patented Nov. 30, 1915.,

` Application f|1edJune'10,.1910; I Serial No.566,'134. v y i which the end journal'boxes of. the locomotive are resiliently connected. vFig.v 7 is a perspective view of one of the side plates forthe end journal boxes. Fig. 8 is a perspective view lof one of the guides for. the journal boxes of the intermediate driving axles, and Fig. 9 is a perspective view of a saddle or bearing'member for one of the` equalizing beams of the locomotive.

' The cab 1 of the locomotive is carried upon a main truck frame comprising two trussed side members 2 that are 'located outyside of the driving wheels Sand 4, and end and intermediate cross members 5 iii the form of plates, girders and braces, The side members 2 of the main frame comprise an' upper'and a lower pair' of channelshapedgirders 6 and 7 that are` connected together by end members 8, intermediate posts 9, and arches 10 and Il, as well -as by the cross members 5. yEach ofthearches 10 consist of two pressed steel arched members 12 that are disposed lside-by-side, angleplates 13 secured to the inner-v faces of the leg and footportionsof said members and sides of the journal boxes 18 upon the ends of axles 19, the springs 16 constituting re- I silient connections between the journal boxes 18 and the main frame of the locomotive,

which connections permit of relative hori# zontal movementv between thev connected' parts.

members 20, to which the -arched .nxemloers The arches 11'are similar to thearches 10, but do not have as lgreat a span, andthe ,95

12 are secured, areprovidedwith raised portions 21 that serve as pedestal legsor guides for journal boxes 22 upon the ends of axles 23, shoes 24 being securedto the .raised por-j,`

tions 21 in order to protect them from wear;v

The journal boxes v22 are thus permitted to have a vertical movementv with respect'to the arches and main frame, but are not permitted to move horizontally withf'respect thereto.

Extending longitudinally between, "and fastened at-their extremities to, the v,arches f 10 and 11, and also between the archesf-f11 and the posts 9 are channel-shaped lattice members 25, located between which, and attached thereto, at the point of crossing, are saddles 26 (Fig. 9) that serve as seats or bearings for. the middle or intermediate points of equal beams 27 and semi-elliptic springs 28.

Bearing upon the journal boxes 18 are posts 29 that support, at their centers, semielliptic springs 30 upon the ends of which suspension bars or rods 31 and 32 have beaihv ings, the lower ends of the suspension rods 32 being connected to the equal beams 27. The lower ends of the suspension rods 31 are pivotally connected to the main frame of the locomotive by means of pins 33 that extend between the pressed steel members 12 of the arches 10. The suspension rods 31 extend somewhat above the semi elliptic springs30, and are connected, at their upper ends, tothe ends of links 34 that are, in turn, pivotally connected at their'other ends to the cab 1, or to any other suitable part of the locomotive that is immovable with respect to the lower ends of the suspension rods 31; I v

Supported upon the journal boxes 22 are dolphin bars 35 that are connected, at their extremities, by means of linksv36 and 37, respectively, to the equal beams 27 at the ends opposite the connections of the suspension bars32 thereto, and to the extremities of the Senn-elliptic springs 28. The other extremities of the semi-elliptic springs 28 have bearings for the lower ends of suspension rods 38 and 39. The two ends of the locomotive differ from each other only in the matter of equalization, which can be best explained at this point.

e suspension rods 38 of one-half of the locomotive are connected, at their upper ends, to the opposite extremities of an equalizing lever 40 that is pivoted, at its middle point, to the main frame ofthe locomotive. The suspension rods 39 of the other half of the locomotive, only a small portion of which is shown, are connected directly to the locomotive frame, the rods. 39 being shorter than the bars 38. Thus, the effect of a three point support of the locomotive frame upon the driving axles is obtained, one point of the support being above the-driving wheels 3 and 4 at the end of the locomotive that is completely shown in Figsjl and 2 and the other two points of support being at the sides of the locomotive above the two-pairs of driving wheels at the opposite end of the locomotive, only a small portion of which is shown.

The driving wheels 3 and 4 are mounted upon the axles 19 and 23, respectively, which are hollow and through which extend tie rods 44 having threadedlextremities for the reception ofnuts 45,'the journal boxes at the extremities of the axles being thus tied together, so that, upon the occurrence of longitudinal or horizontal movement of the axle, the journal boxes will move therewith. This feature is covered in an application Serial No. 537,244,led Jan. 10, 1910, by Hans G. Berensten and assigned to the Westinghouse Electric & Manufacturing Company. p

The axles 19 and 23 are surrounded'by quills 46 for which bearings 47 are provided in the sides of propelling motors 48 -and 49 that are operatively connected thereto by means of gears 50 and pinions 51. The outer faces of the gears 50 are provided with studs 52 that project into sockets in the driving wheels and are surrounded by helical springs--53, adjacent convolutions of which are eccentrically disposed with respect to each other, as set forth in Patent No. 817,133. The motors are supported at the sides or ends opposite the bearings 47 by mea-ns of hanger rods 55 that are provided near their ends with seats 56 and 57, between which and supports or brackets 58 on vthe main frame, are interposed helical compres- 'sion springs 59 and 60. The motor 48 is also provided, at the end opposite the bearings 47, with an apertured lug 61 having a pivotal connection to a box 62 that fits in and is capable of movement both vertically and longitudinally ofthe locomotive in a vertically slotted bracket 63 that is fastened to the adjacent end of the motor 49. The motor 48 is thus permitted to move vertically, Within the limits of compression of the springs 59 and 60, and to move longitudinally of the locomotive within the limits of compression of the springs 16, while a pivotal point is provided about which the motor, driving axle and associated parts may swing horizontally with respect to the main frame of the locomotive. The pivotal point is also independent of the main frame of the locomotive, so that a comparatively great freedom of movement is permitted, without strain upon the locomotive parts. The end of the motor opposite the bearings 47.is further provided with a stirrup 64 that extends through a space which is provided between the bracket 63 and the motor 49,

which stirrup serves to support the motor in case the suspension means becomes broken or injured.

From the description and the drawings, it will be apparent that the end driving axles and wheels are capable of horizontal movement with respect to the main frame, and that this movement occurs with practically no friction, though it is restrained by the springs 16. Further restraint and normal maintenance of the said parts in a central position with respect to the main frame "is effected by means of centralizing springs 66. y

All of the ymotors are resiliently supported, while the end motors are pivotally attached to parts other than the main frame in a ymanner that provides for greater freedle, that is attached` thereto at the points of 215, thereto; and resilient connections between.

crossing, provides `a simple and eective bearing for the equal beams. A
